@MockBean doesn't work with @Timed annotated components

[chornyi]

Similar to #6405

When applying @MockBean annotation to a component that has methods annotated with com.codahale.metrics.annotation.Timed, following exception is thrown on application startup:

The bean 'BeanName' could not be injected as a 'com...BeanName' because it is a JDK dynamic proxy that implements:


Action:

Consider injecting the bean as one of its interfaces or forcing the use of CGLib-based proxies by setting proxyTargetClass=true on @EnableAsync and/or @EnableCaching.

This application does not use @EnableAsync or @EnableCaching. This is with Spring Boot 1.4.0.RELEASE

Found a solution. Similar to @EnableAsync, setting proxyTargetClass = true fixes the issue:

@EnableMetrics(proxyTargetClass = true)

Reopening so that we can see if we can make this easier
